Posix' "mv" command does work differently than rename. I use the above
trick
all the time to "rename" udc files (and even program files) that are in
use
so I can replace them for subsequent openers.

From mpe;

:MV.HPBIN.SYS "UDCFILE OLDUDC"
:RENAME NEWUDC,UDCFILE

mv works even on files that are in use (just like Posix' "rm" can delete
a file that's in use - unlike :PURGE).

We even use the mv "trick" in our NetMail/3000 update scripts to allow
updates to be done without even making everyone "get out" of the
application.
